fungus that has saclike asci that house ascospores.

A sexual spore from certain fungus species in which spores are found in a sac called an ascus. haploid spores found in the asci of ascomycete fungi.

In fungi, a sac that encloses a tetrad or an octad of ascospores. The sac in ascomycete fungi that holds the ascospores.

Asparagine is an uncharged polar amino acid. The asparagine-hydroxylation modulates interaction with other activators, whereas the proline-hydroxylation targets HIF-1 for destruction in proteasomes. Asparagine deamidation is another PTM that must be monitored for changes over time. Deamidation entails the chemical cleavage of the amide group from the asparagine side chain, typically converting that residue to an aspartic acid or isoaspartic acid. As with isomerization, this degradation can be more impactful if the modification occurs on a CDR residue (or the reactive site of a recombinant protein) because it risks affecting activity. Asparagine is a nonessential amino acid used in the biosynthesis of proteins. The precursor of asparagine is OAA. Deamidation of asparagine and glutamine can also occur during sample preparation, and deamidation is often listed as frequent posttranslational modification in error-tolerant searches. Moreover, asparagine and lysine share a twofold degenerate codon box in the Universal Genetic Code.

Synonyms:L-alpha-aspartyl-L-Phenylalanine methyl ester Aspartame is made from two Amino acids and methanol. When it is digested, it breaks down into these three parts. Amino acids are the normal breakdown products of Proteins. Aspartame is a low-calorie sweetener used in many foods and drinks. Because it is between 160 and 200 times sweeter than sugar, only very small amounts are needed to sweeten a product. A typical 12 ounce low-calorie soft drink will have 180 milligrams of Aspartame in it.

Aspartic acid is a negative polar amino acid

A compound that is part of a group of drugs called salicylates. aspirin is widely used for relieving pain and reducing fever in adults. It also relieves mild itching and reduces swelling and inflammation. Use of aspirin by children has been linked to the occurrence of a disorder known as Reye’s syndrome.

The analysis of a substance or mixture to determine its constituents or their level.
