describe

N-Acetyl-L-methionine is a derivative of L-methionine, which is L-methionine in which one of the amine hydrogens is replaced by an acetyl group. It has the function of nutritional supplement. It is N-acetyl-L-amino acid, L-methionine derivative and N-acetylmethionine. It is the conjugate acid of N-acetyl-L-methionine (1-). It is the enantiomer of N-acetyl-D-methionine.

N-acetyl-L-methionine is a metabolite found or produced in Escherichia coli (strain K12, MG1655).

N-acetyl-L-methionine is a natural product found in Arabidopsis thaliana, ginseng, and other organisms for which data are available.

N-acetyl-L-methionine is a human metabolite that is nutritionally and metabolically equivalent to L-methionine. L-methionine is an indispensable amino acid required for normal growth and development.

N-acetylmethionine is an amino acid used in the peritoneal dialysis treatment of patients with renal failure and in the nutritional therapy of patients with nutritional deficiencies or debility following infection.

N-acetyl-L-methionine is an excellent protector of human serum albumin against post-translational oxidation

Research shows that N- AcMet , N-acetyl-L-methionine is excellent at scavenging reactive oxygen species and protecting proteins from oxidation. N-AcMet has a good stabilizing effect on protein structure and its antioxidant properties. The reduction in oxidized recombinant human serum albumin (rHSA, Recombinant human serum albumin) burden helps maintain normal pharmacokinetics. Therefore, N-AcMet should be useful as a novel stabilizer and antioxidant for albumin and other solubilized protein preparations. It is expected that N-AcMet will be approved as a new stabilizer in the near future.

經痛治療點解咁多年都冇突破?最新方法、本地現況與未來方向

經痛治療點解咁多年都冇突破?最新方法、本地現況與未來方向

幾乎一半嘅世界人口,每個月都要面對一次——月經同經痛。由青春期到更年期,呢段時間長達三十幾年。雖然經痛唔係致命疾病,但對好多女性嚟講,每個月都係一次痛苦嘅循環,影響工作、學業同生活質素 [1]。咁問題嚟喇:點解咁多年嚟,經痛治療仲係停留喺熱水袋同布洛芬(ibuprofen)?

Celecoxib(西樂葆)介紹 — 藥理、歷史背景與臨床試驗

1. 藥物簡介與臨床用途 Celecoxib(商品名 Celebrex 等)係一種選擇性 COX-2 抑制劑,屬非類固醇抗炎藥(NSAID)。COX-2 喺炎症反應中會誘導前列腺素生成,從而引發疼痛及發炎;而 Celecoxib 有效抑制 COX-2,但對 COX-1 影響較少,因此相對常見 ...

用粟粉醃肉有乜科學根據?揭開中菜「滑肉」嘅秘密

前言:點解中餐炒肉咁滑? 好多香港人炒肉嘅時候都會發現,餐廳啲雞絲牛柳炒出嚟特別滑溜、唔鞋口。呢個秘密,唔喺高級食材,而係一個平凡但強大嘅材料——粟粉(Cornstarch)。 呢種技巧叫做**「走油前醃」或「滑油醃肉法」(Velveting)**,係中餐獨有技術之一,主要靠粟粉、蛋白、調味料...
咩係三價鐵(Fe³⁺)同二價鐵(Fe²⁺)?

咩係三價鐵(Fe³⁺)同二價鐵(Fe²⁺)?

當我哋講「鐵質」時,唔止係話有冇攝取足夠,而係講緊鐵喺人體內唔同形態(尤其係三價鐵 Fe³⁺ 同二價鐵 Fe²⁺)點樣被吸收、轉化、運輸同儲存,呢啲都深深影響生物可利用率

全面解構低鐵原因、病理機制及影響

低鐵唔止係營養問題,仲可能係身體慢性警號

鐵質(iron)係人體不可或缺嘅微量元素,主要負責攜帶氧氣嘅血紅素(hemoglobin)製造、能量代謝、免疫調節等。當鐵質長期攝取不足、吸收差、或失去過多,就會導致「低鐵」(iron deficiency)甚至發展成「缺鐵性貧血」(iron deficiency anemia)。本文將從臨床醫學與分子生理角度,深入探討低鐵嘅成因、病理機制、生物轉化過程,以及其對人體造成嘅連鎖影響。

夢遺係唔係一定關性事?

夢遺,即係在無意識之下於睡眠中射精,係一種常見於青春期男生甚至成年男性身上的自然生理現象。夢遺唔等於一定發生性夢,也唔等於有性慾過強。它與睡眠週期中快速動眼期(REM sleep)嘅勃起模式有關,亦可能反映正常的荷爾蒙波動及精液排出節律。 咩係夢遺? 夢遺(nocturnal emission...

唔凍都會打冷震?

打冷震(shivering)唔一定因為天氣凍,喺情緒波動、發燒初期、焦慮、緊張等情況下都可以出現。打冷震係一種由大腦下視丘控制嘅「非意識性肌肉收縮」,目的係維持或調節核心體溫或應對突發壓力。了解打冷震背後嘅神經與體溫調節原理,可以幫我哋區分「正常生理反應」同「潛在疾病警號」。 打冷震係乜回事...
一緊張就流手汗?

一緊張就流手汗?

手掌汗腺主要受交感神經系統控制。當人面對壓力、驚訝、社交場合等刺激時,大腦會啟動「戰鬥或逃跑反應」,促使手掌、腳底等部位產生明顯出汗。這種情況屬於精神性出汗,與溫度無直接關係,係身體對外在壓力的自然反應。
