A Novel HILIC‐UPLC‐DAD‐MS/MS Method for the Analysis of Mycosporine‐Like Amino Acids and Their Quantification in Diverse Algae

ELECTROPHORESIS
ABSTRACT Mycosporine‐like amino acids (MAAs) are photoprotective compounds primarily produced by marine organisms, especially red algae. Chemically, MAAs and their precursors are low‐molecular‐weight natural products that absorb ultraviolet radiation in the range of 270–360 nm without generating free radicals ...

Changes in protein N-glycosylation during the fruit development and ripening in melting-type peach

Food Materials Research, 2021
The posttranslational modification of proteins with complex carbohydrate moieties (glycosylation) regulates the process of fruit ripening. Exoglycosidases are enzymes that can trim this protein glycosylation and are therefore considered to be important ...
