| 영문 | acid | 한글 | 산 |
|---|---|---|---|
| 설명 | 물에 녹았을 때 이온화하여 수소 이온을 만드는 물질. 신맛이 나고 청색 리트머스 종이를 붉게 변화시키며 염기와의 중화 반응에 의하여 물과 염을 만들고 이온화 열에서 수소보다 앞에 있는 금속과 반응하여 염을 만들면서 수소를 발생시킨다. 수소 원자를 이온화하는 힘의 강약에 따라 강산과 약산으로 나뉜다. |

| 영문 | acetic acid | 한글 | 아세트산, 초산 |
|---|---|---|---|
| 설명 | 분자식은 C2H4O2, 분자량 60.05의 저급 지방산이다. CH3COOH의 구조식을 가진 무색액체로 16.7℃에서 녹고 118.0℃에서 끓는다. 식초의 신맛을 내는 것이고, 농축된 것을 빙초산이라 한다. 상온에서는 액체이며 수용액은 약산성이다. 생체내에서는 일반적으로 아세틸 CoA로 존재하며 아세틸기의 공급원이 되는 외에 지방산이나 스테로이드 등의 생성재료로 중요하다. 아세틸 CoA로부터는 케톤체가 합성되며 조직의 에너지원이 된다. |

|---|---|---|---|
| 설명 | 상품명이 아스피린(asprin)인 약. 대표적인 비스테로이드 항염약이다. 즉 항염증(anti-inflammatory), 진통(analgesis), 해열(anti-pyretic)의 효과가 모두 뛰어나지만 위장장애, 과다호흡, 라이증후군(Reye syndrome) 등의 부작용이 있다. |

| 영문 | uric acid | 한글 | 요산 |
|---|---|---|---|
| 설명 | 결정성의 산. 2, 6, 8-trioxypurine. 화학식은 C5H4N4O3로 사람과 동물의 오줌에서 얻을 수 있다. 핵의 대사산물의 하나. 물, 알콜, 에테르(ether)에는 거의 녹지 않으나 알칼리염의 용액에는 녹는다. 이것의 나트륨염 형태(sodium urate)가 결석의 대부분을 차지한다. 급성백혈병 치료 초기단계와 통풍(Gout)에서 혈중요산이 급격히 오를 수 있다. |

| 영문 | acid-fast bacillus | 한글 | 항산막대균, 항산균 |
|---|---|---|---|
| 설명 | 아닐린 색소에 염색되기 힘드나 일단 염색되면 강산으로 처리하여도 탈색되지 아니하는 세균을 통틀어 이르는 말. 결해균, 나병균 따위가 있다. |

| sperm-ovum interactions | Interactive processes between the ovum and the spermatozoon. (12 Dec 1998) |
|---|---|
| sperm tail | The posterior, filiform part of spermatozoa, which provides sperm motility. (12 Dec 1998) |
| sperm transport | Passive transport or active migration of spermatozoa from the testes through the male genital system as well as within the female genital system. (12 Dec 1998) |
| sperm whale | <zoology> A very large toothed whale (Physeter macrocephalus), having a head of enormous size. The upper jaw is destitute of teeth. In the upper part of the head, above the skull, there is a large cavity, or case, filled with oil and spermaceti. This whale sometimes grows to the length of more than eighty feet. It is found in the warmer parts of all the oceans. Called also cachalot, and spermaceti whale. Pygmy sperm whale, a toothed cetacean (Hyperoodon bidens), found on both sides of the Atlantic and valued for its oil. The adult becomes about twenty-five feet long, and its head is very large and thick. Called also bottle-nosed whale. Source: Websters Dictionary (01 Mar 1998) |
| nematode sperm | The nematode Caenorhabditis elegans has an unusual amoeboid spermatozoon that is actively motile yet appears to lack both actin and tubulin. (18 Nov 1997) |
| intracytoplasmic sperm injection | <gynaecology> The direct injection of a single sperm into an egg. (09 Oct 1997) |
| acid phosphatase | <enzyme> An enzyme that catalyses the conversion of an orthophosphoric monoester and water to an alcohol and orthophosphate. Chemical name: Orthophosphoric-monoester phosphohydrolase (acid optimum) Registry number: EC 3.1.3.2 (12 Dec 1998) |
| acid phosphatase test for semen | A screening test for semen by determining acid phosphatase content; because seminal fluid contains high concentrations of acid phosphatase, while other body fluids and extraneous foreign materials have very low concentrations, high values of acid phosphatase on vaginal aspirate or lavage, or on wash fluid from stains, render positive identification of semen, even if the male is aspermic. (05 Mar 2000) |
| Gomori's non-specific acid phosphatase stain | <technique> A method in which formalin-fixed frozen sections are incubated in a substrate containing sodium beta-glycerophosphate and lead nitrate at pH 5.0; the insoluble lead phosphate produced is treated with ammonium sulfide to give a black lead sulfide. (05 Mar 2000) |
| prostate acid phosphatase | An enzyme produced by the prostate that is elevated in some patients with prostate cancer. (12 Dec 1998) |
| purple acid phosphatase | <enzyme> 110-kD glycoprotein with fe(iii)-zn(ii) centre; isolated from the red kidney bean phaseolus vulgaris; genbank p80366 Registry number: EC 3.1.3.- Synonym: tartrate-resistant purple acid phosphatase, fe(iii)-zn(ii) purple acid phosphatase, kbpase (26 Jun 1999) |
| okadaic acid-sensitive phosphatase | <enzyme> Negatively controls the cyclin degradation pathway in amphibian eggs Registry number: EC 3.1.3.- Synonym: oas-phosphatase (26 Jun 1999) |
| tartrate-resistant acid phosphatase | <biochemistry, enzyme> Acid phosphatase is present in bone, prostate, platelets, erythrocytes and spleen. Osteoclasts contain an isoenzyme that is resistant to tartrate, whereas, the isoenzyme in the prostate is sensitive. Tartrate-resistant acid phosphatase is elevated in the serum of patients with primary hypoparathyroidism, Paget disease, vertebral osteoporosis, T-cell lymphoma and in women after oophorectomy. Oestrogen replacement in osteoporotic postmenopausal women is associated with a decrease in tartrate-resistant acid phosphatase of 70% over 3 to 6 months. Acronym: TRAP (16 Dec 1997) |
